The “Première Kyrie” (First Kyrie) is the opening piece of this organ mass. “Chromhorne sur la Taille” (Cromorne on the tenor) is a piece that require a solo reed stop, equipped on typical organs. The cromorne stop has a buzzing sound similar to that of an oboe or clarinet. Since there is not a solo reed stop at Grace, we have to use alternative stops. This shows the importance of our pipe organ project, which will help us acquire some essential and colorful reed stops.
